Abstract: This invention provides a matrix scaffold for three-dimensional (3D) cell cultivation, a method of its construction, and its uses. The matrix scaffold results from a crosslinking reaction of a fibroin-like substance prepared by a specific method from silk cocoons or filaments, chitosan and crosslinking agents. This matrix scaffold is more advantageous in terms of degradation stability and benefits to 3D cell cultivation over existing matrix scaffolds. In addition, it can replace extracellular matrices (ECMs) or tissue and organ matrices and is further for use for the in-vitro differentiation and proliferation of cells, tissue and organ reconstruction and antitumor drug screening.

Abstract: A sterile and instantly dissolvable drug membrane, a method thereof for testing drug sensitivity of antineoplastic drugs, and an application thereon in testing drug sensitivity of antineoplastic drugs are provided, wherein the method for testing drug sensitivity of antineoplastic drugs includes steps of: dissolving an antineoplastic drug in a cell culture fluid comprising tumor cells, in such a manner that the antineoplastic drug fully contacts with the tumor cells; wherein the antineoplastic drug is prepared into a sterile and instantly dissolvable drug membrane for being dissolved in the cell culture fluid. According to the present invention, the antineoplastic drug is prepared into a sterile and instantly dissolvable drug membrane for testing drug sensitivity of the antineoplastic drugs, which improves operation efficiency, flexibility, accuracy and economy of drug sensitivity test of the antineoplastic drugs.
